Description
Technical field
The present invention relates to the lock body of door lock, Door lock that particularly can the oblique dead bolt of reverse drive.
Background technology
Security door and theftproof lock thereof are brought into use on market, but these lock bodies due to its inner space limited and its internal driving mechanism complicated especially, be difficult to its inner driving mechanism of rational deployment.
Summary of the invention
For the deficiencies in the prior art, make it not only topology layout is rationally but also can oppositely regain described oblique dead bolt thereby one of purpose of the present invention is to improve the driving mechanism of lock body.Described oblique dead bolt can be recovered in lock body when the oblique dead bolt of described reverse withdrawal refers to turn clockwise lock gall, stretch out described lock housing body and can drive Square lock bolt when counterclockwise rotating lock gall.
For this reason, the present invention proposes the Door lock of the oblique dead bolt of a kind of reverse drive, and described lock body comprises the lock housing body, is contained in the driving mechanism in described lock housing body, oblique dead bolt and Square lock bolt, also comprises the lock gall that can drive described Square lock bolt; Described oblique dead bolt is positioned at the right side of described Square lock bolt, described oblique dead bolt comprise rod body part and be arranged on described rod body part front end and the bevelled head of tool, described driving mechanism can drag in the peristome that the head of described oblique dead bolt forms on the face sidewall of described housing and stretches out or retract; It is characterized in that, described driving mechanism includes the connecting lever that can regain described oblique dead bolt, can drive the pusher arm that described connecting lever rotates and be arranged on described Square lock bolt and the conductive arm that can move on described Square lock bolt; Described connecting lever comprises transverse arm, the rod body part interlock of described transverse arm and described oblique dead bolt; Described pusher arm is the both arms shape, and its tail end is connected with described transverse arm, and its top ends is connected with described conductive arm; Described lock gall is arranged between described Square lock bolt and described oblique dead bolt; The shift fork clockwise direction of described lock gall can promote described conductive arm when rotating and move, and then oppositely regains described oblique dead bolt, can promote described Square lock bolt when the shift fork of described lock gall counterclockwise rotates and stretch out.
Wherein, clockwise described or counter clockwise direction is that the page in embodiments of the invention is the direction of benchmark.Described Square lock bolt refers to the dead bolt that its head that stretches out is square.
According to said structure, be connected to the top ends of described pusher arm due to described conductive arm, regain when opening described lock gall like this and open oblique dead bolt.Secondly, because described conductive arm is arranged on described Square lock bolt movably, the space of so not only having saved in lock body makes described driving mechanism rationally distributed, can also make described conductive arm move and break away from the top ends of described pusher arm with described Square lock bolt, could rely on the oblique dead bolt of described lock gall withdrawal after realizing regaining described Square lock bolt.
Further technical scheme can also be that described conductive arm can be arranged on described Square lock bolt with moving left and right.
Further technical scheme can also be, the top ends of described conductive arm is the connecting lever shape, and the top ends of described pusher arm can stretch in the connecting lever groove of described conductive arm top ends.
Further technical scheme can also be, described conductive arm is the L shape and can rotates on described Square lock bolt, and the back of described conductive arm leans the top ends at described pusher arm.
Further technical scheme can also be, on described rod body part, block is set, and described transverse arm is combined on described block.
Further technical scheme can also be, is set with back-moving spring on the tail end of described rod body part, and described back-moving spring is limited between described block and described housing.
Further technical scheme can also be, the axis of rotation position of described connecting lever is provided with the rotating shaft of door handle.Like this can be by the described oblique dead bolt of the unlatching of described door handle.
Because the present invention has These characteristics and advantage, can be applied in the structure of safe-guard door lock for this reason.
